Abstract

The shaping membrane (5) is tensioned at both ends and limits a pressure chamber (2) fed from a hydraulic pressure source. A ring gap above the shape hollow space (12) between the pressure pot (1) and the steel mandrel (11) is blockable and limitable by means of a cylindrical, vertical steel ring (13) movable in and out. The ring gap beneath the shape hollow space between the pressure pot and the steel mandrel is blockable and limitable by means of a conical, vertically movable steel ring (15). After isostatic pressing of the ceramic pulp in the shape hollow space, the steel mandrel (11) together with the lower conical steel ring (15) and the ready pressed product (26) moves vertically downwards.
